Hit Point, Spell Slot Tracker

This a remix of Nissenko's awesome Hit Point-Spell Slot tracker from Thingiverse.  My intention was to make it more easily customizable and (re)configurable with various length of Cores onto which End Caps are press fit, and thin spacers separate groups of digits.  This allow you to group different arrangements of digit wheels, including a fixed double row, for example:

Single Rows:

• 3 digits (Hit points 000-999, or Spell Slots for Levels 1-3)
• 2 Digits (Temp Hit Points) - Separator - 3 Digits (Hit Points)
• 3 Digits - Separator - 3 Digits (Spell Slots for Levels 1-6, or Hit Points + Spell Slots 1-3)
• 3 Digits - Separator - 3 Digits - Separator - 3 Digits (Spell Slots for Levels 1-9, or Hit Points + Spell Slots for Levels 1-6)

Double Row:

1. Upper…3 Digits + Separator + 3 Digits  (Spell Slots for levels 1-6)
2. Lower…3 Digits + Separator + 3 Digits (Spell Slots for levels 6-9, + 3 Digits can be for Concentration Y/N + Spell Casting Modifier + Spell Save DC using the Y/N and 10-20 Tiles).

The Cores are sliced at lengths to include 2mm separators as described above, but since the Cores are separate parts, they can be adjusted shorter or longer as you desire by adjusting the Z values, if for instance you want to omit the separators.  Including the Separators at every third digit makes it easier to count to specific spell level at a glance.

One version of Digit Wheel has recessed numbers 0-9 that can be filled with paint for better visibility.  There is also a version of Digit Wheel that is blank with indentations to glue in tiles 0-9, 10-20, and Y-N letters)…apologies for the font differing slightly for the 10-20 tiles.  Printing the number tiles separately allows for easy color printing for improved visibility.  There are also two versions of ease of turning/locking the Wheels.  The Tight Wheels more firmly snap into position and stay in place, but require more effort.  The Smooth Wheels are easier to turn, but with less security and can more easily be accidentally moved.

Pics show just a few of the configurations of digits for Hit Points, Spells Slots, Spell Casting Modifier, Spell Save DC, active Concentration.

Cores of varying lengths that are press fit into end caps that allow multiple configurations of digit wheels and thin separating spacers.  Added a fixed dual row end caps option.  Added number tiles for 10-20, and Y, N)
